JOHN w. GRAHAM,

OF HIN'I'ON, WEST VIRGINIA.

TYPOGRAPHICAL OR LINE-CASTING MACHINE.

Application filed May 12, 1915.

To all whom it may concern:

Be it known that I, JOHN W. GRAHADI, a citizen of the United States, residing at Hinton, in the countyof Summers and State of WVest Virginia, have invented certain new and useful Improvements in Typographical or Line-Ca-sting Machines, of which the following is a specification.

My invention relates to typographical or linecasting machines, such as linotypes of the original construction; wherein circulating matrices are released from a magazlne in the order in which their characters are to appear in print, and then assembled in line together with expanding spacers, the composed line brought in contact with the face of a mold, the mold filled with molten metal to form a line of type or slug against the matrices, which produce the type charactersthereon, and the matrices thereafter returned to the ma azines from which they were originally rawn.

More particularly it relates to that class of machines, having a series of magazmes, any one of which can be brought into operative position, and wherein the magazines are removable and interchangeable, and to that end are mounted on a spider or rack, such spider or rack being mountedupon a shaft, housed at the front and rear on bearings aifixed to the frame of the machine, to

allow the magazines to revolve into exact opcrative position.

In the drawings I have shown my inven tion as applied 'to a linotype machine but, obviously, it may be applied to other machines such as typesetters and typecasters, and many changes and variations could be made therein without departing from the spirit, or principle of this invention.

Referring to the drawings Figure 1 is a side view of a portion of a linotype machine having my invention applied thereto. Fig. 2 is a front view of the main arm of the machine, showing the casting which houses the hearing at the front, and part of the casting at the back which supports the rear bearing. This view also shows a magazine in the rack, in operative position. Fig. 3 is a side view of a section of magazine with a verge in place, and the trip finger which trips the verge. Fig. 4c shows the locking device. Fig. 5 is a view of the rack or spider. Fig. 6 is a side view of a section of an angle iron upon which the magazine rests, showing the slots to engage the extended ends, of the Specification of Letters Patent.

strengthening bar. Fig. 7 is a fragmentary plan view of a part of a magazine with its strengthening bar. Fig. 8 is a perspective view of a section of a magazine showing the projecting end of the strengthening bar, which is designed to engage the slot in the angle iron side, of the basket.

Referring to Fig. 1: A is the main arm of the machine.

A is a cross arm bolted or otherwise securely aflixed to the main arm A.

A represents the forked arm which supports the shaft G at its frontal end.

A is an arm already on all machines of the class described, and from which is extended the supporting arm A A shows magazines mounted in place on rack H.

Referring to Fig. 3:

T represents a verge in place, holding matrix V in place.

V representsa trip finger.

V represents a slotted key rod.

V represents a pin, on which the finger V is pivoted.

V represents a spring, to hold the finger V in place.

V represents a spring, to hold the verge V in place.

V represents a casting, in which the finger V is housed.

Referring to Fig. 4:

P shows the lock pin housed in the east ing V I In operating the machine the pin P shown in Fig. 4 is withdrawn and the desired magazine turned to operative position. The pin P is then allowed to enter socket, in the magazine, thus locking the magazine in place. This socket is a hole in the bar which houses the verges, and the hole is so placed near the end of the bar that when the pin P is socketed in said hole the magazine is in operative position. Each of the magazines is made with a like hole or socket. To remove the magazine from the rack or spider, which is herein shown in the form of a truncated triangular pyramid, the magazine is moved back in its wedge shaped support a distance, sufficient to allow the extended ends of the strengthening bars H to become disengaged from, the slots H in the rack bars H The magazine is then lifted up to allow these projections H to pass over the top of the angle irons H and allow the magazine to be removed.

The verge V shown in Fig. 3 is so constructed as to hold the outmost matrix in place with its front pawl, its rear pawl rising up between the ears of the neXt matrix, when the escapement mechanism is tripped. The verge V is tripped by the trip finger V which is housed in a slot in the casting V and the spring V also rests in the said slot in the casting V The finger V is connected to the key rod V by the pin V and the said key rod'V is slotted vertically where it connects'with the pin V Having described my invention, its construction and operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical machine the combination of a plurality of removable magazines, housed on a spider or rack, said rack made in the general form of a truncated, triangular pyramid, and means whereby said rack may be rotated to bring the magazine into operative position.

2. In a typographical machine the combination of a plurality of removable magazines, a spider or rack in which said magazines are housed, said rack made in the general form of a truncated, triangular pyramid, a shaft permitting rotation of said rack, bearings afiixed to the frame of the machine, one at the front and one at the back, supporting said shaft, whereby the spider or rack can be revolved to bring any desired magazine into operative position.

8. In a typographical machine the combination of a plurality of removable magazines having projecting strengthening bars, a spider or rack in which said magazines are housed constructed in the general form of a truncated, triangular pyramid, angle iron rests supporting said magazines, having slots to engage the projecting ends of .saidstrengthening bars of the magazines, adapted to hold said magazines in place, both horizontally and vertically.

4. In a typographical machine the combination of a plurality of removable magazines, a rotatable rack to house said maga zines being made in substantially the form of a truncated polyhedron, a centrally and longitudinally disposed shaft upon and about which said rack is adapted to turn, and rack bars attached to the said rack to hold the magazines in place.

5. In a typographical machine the combination of a plurality of removable magazines, a rack to house said magazines being made in substantially the form of a truncated triangular pyramid, and rack bars attached to said rack to hold the magazines in place having slots therein to be engaged by said magazines.

6. In a typographical machine the combination of a plurality of removable magazines, a rack to house saidmagazines being made in substantially theform of a truncated triangular pyramid, rack'bars attached to the said rack adapted to hold the magazines in place, having slots therein and bars attached to the said magazines having projecting ends to engage slots in said rack bars.

7 In a typographical machine the combination of a plurality of removable magazines, a rack in the form of a truncated triangular pyramid to house said magazines and a shaft extending centrally through the said rack permitting rotation of said rack.

8. In a typographical machine the combination of a plurality of removable magazines, a rotatable rack in the form of a truncated pyramid tov house the said magazines, a shaft extending centrally and longitudinally .through the said rack, and bearings to support said shaft.

9. In a typographical machine the combination of a'plurality of removable magazines, a rotatable rack to house the said magazines, said rack being made in the form of a truncated pyramid, a shaftextending centrally and longitudinally through said rack, bearings to support said shaft and a supporting frame aflixed to the frame of the machine to support the said bearings.

In testimony whereof I afliX my signature in presence of two Witnesses.
